A compact level sensor for corrosive service

The LevelBest compact-mount level sensor and transmitter (photo) has been specifically designed for corrosive-service applications, such as acids or caustics in moist, salty atmospheres. The body is made of 304 stainless steel, with a polycarbonate NEMA 4X electronic and terminal block enclosure that is sealed and separate. Other features include a smart two-wire electronic transmitter with remote HART-like communications; a 2-in. NPT connection; and local or remote calibration over two-wire 4–20-mA signal leads. The device measures over the range of 3 in. to more than 166 ft. The instrument is based on the principle of buoyancy, whereby the LevelBest weighs an inert chain, and determines the inverse of liquid level and converts it to an analog or digital electronic signal for indication, alarming or continuous or on-demand transmission. — Levelese, Inc., Denver, Colo.
